The Alameda Credit Union is pursuing a merger, citing rising costs, new regulations and a desire to provide more services.

The 76-year-old credit union is seeking approval from state and federal regulators to merge with Redwood City-based Provident Credit Union, and will seek its members’ approval if the regulators sign off, according to a letter the credit union’s leaders sent to members Friday.
